Candidate 20260613T025625Z-016

WPQEMGTQWPPNQWQ

Why this candidate advanced

Advanced for computational review because it showed compact fold and low exposed hydrophobic in the immune modulator campaign. This is a structural-prior signal only, not evidence of activity. The current computational decision is promote for review.

Next experimental question

Does this sequence show measurable immune modulator activity, target engagement, or useful stability under controlled assay conditions?
